摘要： A motor drive apparatus capable of detecting a rotor rotation position of a stepping motor, without causing a substantial cost increase. A CPU of the motor drive apparatus determines a difference between a data number, which corresponds to a timing at which an ENC0 or ENC1 signal changes in level when there is no follow-up delay of a rotor relative to voltage signals applied to A- and B-phase coils, and a data number, which corresponds to a timing at which the ENC0 or ENC1 signal changes in level when there is a follow-up delay of the rotor relative to the voltage signals, and corrects the follow-up delay of the rotor based on the determined difference.

摘要： A method is provided for managing at least one transition in a three-phase BLDC motor describing a cycle including six successive states, wherein the motor obtains first, second and third synchronisation signals. The synchronisation signals are respectively associated with first, second and third coils of the motor. The method includes the following steps, for each current transition associated with the switching of the motor from a current state to a next state: selecting a current synchronisation signal on which the current transition is to appear; detecting the occurrence of the current transition on the current synchronisation signal; and sending, to the motor, at least one current control signal so as to switch the motor from the current state to the next state.

摘要： A stop and jamming detection system in a stepping motor determines a parameter from the profile of an instantaneous motor variable and compares it to a reference value. A signal for the stop and jamming detection system is generated therefrom. Provided for this purpose is an analysis circuit which detects, as the instantaneous motor variable, the voltage that is induced in at least one unenergized winding of the stepping motor and is brought about by an energized winding of the stepping motor, and analyzes it as to whether the stepping motor is jammed or movable. In the analysis by the analysis circuit, a decision is made as to a hard or an elastic jam. With a hard jam, the stationary armature means that no voltage is induced, while with an elastic jam, because the step is not completed, the recoil of the armature into its original position induces an opposite-phase voltage peak which is detected.

摘要： A stepper motor controller that controls acceleration of a stepper motor so that, once the stepper motor is stabilized at 500 pps, acceleration of the motor is increased to 667 pps for four steps, during which time the speed of the stepper motor reaches about 900 pps. Then, acceleration of the stepper motor is increased to 1,000 pps, allowing the motor to increase to that speed without degeneration of the speed. In other words, when the stopper motor nears the maximum possible speed at an acceleration of 667 pps, the next acceleration is applied. In this way, acceleration of the stepper motor can be changed between levels having a great difference in driving frequency without causing the stepper motor to degenerate.
摘要翻译：步进电机控制器，其控制步进电机的加速度，使得一旦步进电机稳定在500pps，马达的加速度就增加到667pps四步，在此期间步进电机的速度达到约900pps 。然后，步进马达的加速度增加到1,000pps，使马达增加到该速度而不会降低速度。换句话说，当止动马达以667pps的加速度接近最大可能速度时，施加下一加速度。以这种方式，可以在驱动频率差大的电平之间改变步进电机的加速度，而不会使步进电机退化。

摘要： In a stepping motor drive control mechanism, a step drive command is applied sequentially at irregular intervals to drive a stepping motor. When the step drive command is to the stepping motor the stepping motor is driven by one step angle. According to the response characteristic of the stepping motor, an inhibited period when the reception of the next step drive command is inhibited and a reception period when the reception is enabled are set up. If the next step drive command is applied during the inhibited period, the system waits until the reception period. Then, the stepping motor is driven by one step angle.
